Through the elastic connection component, the pressure plate 8 can be pressed on the workpiece. The elastic connection component can absorb part of the impact force and reduce the degree of force on the workpiece, thereby extending their service life. By setting a plurality of ball bearings 19, during the punching process, the punching head 7 rotates and applies force downward, and the ball bearings 19 can roll and disperse this force, reducing the direct contact area between the punching head 7 and the pressure plate 8, thereby reducing friction and wear.

The top of the connecting tube 12 is provided with a rotating rod 14, and the rotating rod 14 is threadedly connected to the connecting tube 12. The top of the rotating rod 14 is fixedly installed with a rotating plate 18. The mounting plate 6 is close to the connecting tube 12 on both sides thereof and has a first through hole 15.

[0026] Reference Figure 1 - Figure 3 An electric telescopic rod 5 is fixedly installed at the bottom of the support plate 4. The output end of the electric telescopic rod 5 is fixedly connected to the mounting plate 6 through a fixed rod. The electric telescopic rod 5 is electrically connected to the external power supply through an external controller. The electric telescopic rod 5 is usually composed of the following main components: a motor, a transmission mechanism, a telescopic rod body, and a control system. When in use, after receiving a control signal through the controller, the motor starts to run, and the motor converts the rotational motion into linear motion through the transmission mechanism. The transmission mechanism pushes a part of the telescopic rod body to extend outward or retract inward, thereby driving the mounting plate 6 to move up and down, and can drive the mounting plate 6 and the self-tightening drill chuck 13 to move downward, so that the punching head 7 is close to the workpiece for punching.

[0027] Reference Figure 3, a second motor 9 is fixedly installed on the top of the mounting plate 6, and a self-tightening drill chuck 13 passes through the mounting plate 6. The self-tightening drill chuck 13 is rotatably connected to the mounting plate 6, and the output end of the second motor 9 is fixedly connected to the top of the self-tightening drill chuck 13 by a pin or a fastening bolt 16. The model of the second motor 9 is XD-3420-2. The second motor 9 is electrically connected to the external power supply through an external controller. The second motor 9 is usually composed of the following main components: stator, rotor, shaft, commutator, brush, casing, and cooling system. When in use, after power is supplied by the external power supply, the current enters the rotor winding through the brush and the commutator. The current passes through the rotor winding to generate a magnetic field. The magnetic field generated by the rotor interacts with the magnetic field generated by the stator to generate a torque. The rotor starts to rotate under the action of electromagnetic force. The action of the commutator causes the current direction to change periodically to maintain the continuous rotation of the rotor, thereby driving the self-tightening drill chuck 13 and the punching head 7 to rotate, which can drive the self-tightening drill chuck 13 and the punching head 7 to rotate, thereby punching the workpiece.

At the same time, the second motor 9 is started by the controller, and the second motor 9 drives the self-tightening drill chuck 13 and the punching head 7 to rotate. When the punching head 7 rotates, it rotates downward along the ball 19. The ball 19 is made of high hardness and low friction material to improve wear resistance and reduce obstacles during the punching process, ensuring that the ball 19 will not interfere with the normal movement of the punching head 7. The pressing plate 8 and the ball 19 can guide the punching head 7 and support stability when drilling downward.
